In the history of Hungarian marketplace puppetry, the multi-generational activity of the Korngut-Kemény puppetry dynasty is welded to the clarification and purification of the character Vitéz László, alongside the components of the traditional family show, the language, style, and method of the performance. The paper examines the specificities of the marketplace culture and the marketplace puppetry screen, the context of the Városliget and Népliget fun-fairs in Budapest, the emergence of the Vitéz László puppet character, as well as the Vitéz László puppets belonging to the Hincz and the Korngut-Kemény families.
